GAS-BURN ER.

SPECIFICATION forming part of Letters Patent No. 414,180, dated November 5, 1889.

Application filed October 24, 1888. Serial No. 289,038- (No model.)

To all whom it may concern:

Be it known that 1, JAMES BAKER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented new and useful Improvements in Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the acco1npanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to an improved burner for producing light or heat in which a current or currents of heated air are caused to mingle with the ignited gas to oxygenate it, and to the means for regulating the amount of air supplied to the burner, and is particularly designed for use with a heating-stove for which I have made separate application for Letters Patent of the United States, Serial No. 289,037, filed October 24:, 1888.

My invention consists in the combination, with the hollow cylindrical burner having the cap or coverprovided with the extended perforated cylindrical cover, and from which the air passes to the flame, of a central rod for deflecting the *air evenly against the inner wall of the cylindrical burner, and in providing said rod with an adjustable head or valve for regulating the amount of air admitted to the central passage.

It further consists in the combination, with the hollow cylindrical burner having the perforated central air supply, of an outer case provided with perforations, and a deflector for admitting and deflecting air around the outer circumference of the burner, all as hereinafter explained.

In the accompanyingdrawings, Figure 1 is a vertical. section through my improved burner. Fig. 2 is a top view of the same with the cap and perforated cylindrical portion or extension removed.

The cylindrical case A, having a base a, of any desired ornamental configuration is preferably formed of sheet metal, and has connected to its upper edge an extension a, made flaring or tapering outward from its point of connection with the cylindrical case, and which portion at its upper edge is bent to form an annular rim a", hereinafter referred to.

The burner portion B is fitted within the case A and extends from a point within the base to a point slightly above the upper edge of the rim or flange (L This burner is composed of the two cylindrical portions 1) I), connected at their upper and lower edges through an annular rim formed with either the outer or inner cylindrical portions, and forming a space or gas-passage b between the inner Walls of said cylindrical portions, the upper connecting-rim being provided With perforations to form the burner, similar to the Argand burners now in general use, the gas being admitted to the space through a pipe (3, extending through the wall of the case A and into the space 11 The burner portion fits closely within the case A 5 but at its upper end the outer portion tapers inward, leaving considerable space between the inner portion of the flaring extension at and its outer face, forming an air-receptacle D, air being admitted to said receptacle through elongated slots or perforations a, formed in the flaring extension. A wire-gauze or perforated metallic ring w covers the opening between the inner wall of the flaring exten sion and the burner, to divide the air into a series of minute jets before mingling with the gas, the outer edge being supported by the rim a and the inner edge resting against the wall of the burner. A ring or deflector D extends over the gauze or perforated ring and has an outwardly and inwardly projecting flange d cl, the one (1 forming the base or sup port therefor on the rim (0 While the other (1' serves to deflect the air upward and inward against the flame. The lower end of the base portion a is closed by means of a wire-gauze or perforated sheet metal E, and through which the air is caused to pass to the central air passage of the burner. A cylindrical head or cap F, composed either of wire-gauze or perforated sheet metal, is fitted within the upper end of the central air-pas sage, and has a solid head F, said head being made adjustable up and down within the central passage, being held in its adjusted position by means of ribs or lugs f, project a I ng from the inner wall of the burner. A rod )1 cylindrical bar F is connected to the head 1* and extends down therefrom centrally ihrough the air space or passage, and is of my preferred length, and which rod has its ower end screw-threaded, and upon which is nounted a regulating-valve G. This valve is made, preferably, in the form shown, having ts outer face tapering upward and outward or a short distance and then inward and upvard, and by its adjustment upon the rod *egulating the amount of air admitted from 7 he base to the central passage. The wire- ,"auze or covering at the bottom prevents'sud- [en drafts of air to the base, and consequently )rovides a steady and even light.

From the foregoing it will be seen that the ,ir is caused to pass through the opening in he base, as above stated, and from thence to )ZLSS into thecentral passage, being deflected :venly against the Walls thereof, andis then livided into a series of minute jets by passng it through the openings formed inthe cap r cylindrical cover before comingin contact vith the flame. The ail-being heated in comng in contact with the walls of the burner is aused to more readily mix withthe burning ;as,andconsequentlywhileproducingasteady nd even light, also producing a large amount f heat-from an ordinary burner, and this, too, without smoke, The outer air-supply is also heated by coming in contact with the outer wall of the burner, and is deflected inward intothe flame, and by which means a hot current of air is thrown into the flame from 35 all points, causing a very steady and even flame, while increasing the intensity of the heat.

What I claim is- 1. A cylindrical or Argand burner provided with the central air-passage, the perforated cylindrical portion fitting within the same, with the central rod or shaft provided with the adjustable valve, substantially as and for the purpose set forth; 45

2. In a cylindrical or Argand burner, the combination of the centralair passage or supply, the perforated cylindrical portion fitting within thesame, a central rod or shaft provided with theadjustable valve to regulate thesupply of .air to the central air-passage, an outer case provided with perforations, and a deflector for admitting air around the outer circumference of theburner,substantially as set :forth. 5 5

In testimony whereof I affix my signature in the presence of two subscribing witnesses.

JAMES BAKER.
